Guanghao Zhang created HBASE-17077: -------------------------------------- Summary: Don't copy the replication queue which belong to the peer have been deleted Key: HBASE-17077 URL: https://issues.apache.org/jira/browse/HBASE-17077 Project: HBase Issue Type: Improvement Reporter: Guanghao Zhang Assignee: Guanghao Zhang Priority: Minor
When a region server is dead, then other live region servers will transfer the dead rs's replication queue to their own queue. Now the live rs first copy the wals queue to its own znode, then create a new replication source to replicate the wals. But if the queue belong to a peer have been deleted, it copy the queue, too. The current steps is: 1. copy the queue to its own znode 2. found the queue belong to a peer have been deleted 3. remove the queue and don't create a new replication source for it There is a small improvement. The live region server doesn't need to copy the queue to its own znode. The new steps is: 1. found the queue belong to a peer have been deleted 2. remove the queue directly instead of copy it -- This message was sent by Atlassian JIRA (v6.3.4#6332)
